China to build hydroelectric project in southwest

Beijing has approved construction of a hydroelectric project in southwest China that will be the country’s third-largest.

The
approval of the Baihetan plant on the Jinsha River at the border of
Sichuan and Yunnan provinces highlights the government’s commitment to
developing hydropower despite growing concerns about dam’s
environmental and social impact.

The Baihetan project will be
built by the China Three Gorges Project Corp, which also built the
Three Gorges Dam on the Yangtze River and is working on Xiluodu,
another hydropower project along the Jinsha, a Yangtze tributary.

When
completed, Baihetan was expected to have total installed capacity of 12
gigawatts and average annual output of 56bn kilowatt-hours, the China
Three Gorges Project Corp said in a statement on its website.

The
Baihetan project is only slightly smaller than the Xiluodu plant,
China’s second largest hydropower project, which has an estimated
capacity of 12.6 gigawatts and is planned for completion by 2015.

The
Three Gorges Dam, which will have total installed capacity of 18.2GW,
was completed well ahead of schedule in late May. The massive
engineering project has cost roughly Rmb180bn and taken well over a
decade to build.

Demolition of the last temporary building
structure at the Three Gorges Dam took place on Tuesday afternoon and
was widely reported in official media. The dam has generated much
controversy over the years due to the mass relocations and inundation
of river towns it has required and the risk of further silt and
pollution accumulating in the Yangtze.

The Xiluodu project has
also been controversial. Early last year, that project came under the
close scrutiny of the State Environmental Protection Administration
(Sepa), which accused it of failing to carry out a proper environmental
impact assessment. The project continued, however.

While China’s
government is still easily able to order large-scale engineering
projects that might be politically impossible in democratic nations,
concerns over dams’ environmental and social impact has been growing in
recent years.

Zhu Guangyao, Sepa vice minister, also said earlier
this week that plans for a series of hydropower projects along the Nu
River, which runs from southwest China into south-east Asia, were being
reviewed.

He said the projects will undergo “substantial changes”
from their original plan from 2004, when Beijing ordered a halt to
construction due to worries over their effect on the environment.

Some
areas surrounding the Nu River, which is known as the Salween in
south-east Asia, are well-known for being rich in biodiversity.

“The
state encourages orderly exploitation of hydropower resources and has
reset energy development strategy,” Sepa said in a white paper released
this week.
